Specification of Letters Patent.

Patented July 9, 1907.

Application filed May 4,1907. Serial No. 371.852.

To all whom it may conccm:

Be it known that we, ROBERT H. OLD and WILLIAM J. LEDERLE, residents of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented Certain new and useful Improvements in Vault-Lights; and we do hereby declare the following to be a' full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

The invention relates to vault lights, and has for its object to simplify and cheapen the construction, and increase its durability.

The invention consists in the construction hereinafter described and particularly pointed ont.

In the accompanying drawing which illustrates the improvement and forms a part of this specification, Figure l is a plan showing the general arrangement of the supporting frame, and partly in section to show tiles set in cement; Fig. 2 is a longitudinal section on line 2, 2 of Fig. l; Fig. 3 is a cross section on line 3, 3 of Fig. l; Fig. 4 shows a detail enlarged. Figs. 5 and 6 are end views, also enlarged, showing pockets of different cross sections.

A denotes flat steel bars, and B rods passing through and connecting them to form a frame. The bars A may be termed the carrying or main bars, as the entire load is supported on them. The rods B which may be styled glass or cement-supporting rods or tie rods, are spaced at distances apart to Suit the size and shape of Between and below the rods B pockets C, made either of sheet or cast metal, are provided. These may be made of either rectangular, curved or V- shape in cross section, and supported on said rods by over-hanging flanges C/ as shown in Fig. 2. They admit a putty filling H, before being placed in position.

This putty or the like acts as a cushion for the glasses E which rest upon the flanges C after the pockets are placed upon the rods. Portland cement and sand, F, of formula, such as known to the trade for this purpose,

40 or ifs equivalent, is introduced between the glassse and use of a rod or rods D.

displacement of the glasses and filling, in case the panels are turned upside down in handling or shipping, or meet with any rough usage. Each glass E may be of any desired shape or size. but preferably has a projection around its sides or edges of such form as to engage in the cement filling whereby they may be supported independently of the bearing on the pockets and rods.

Standard stock material can be employed to make the frame, and sheet metal pockets can be easily formed by au ordinary tinners folder or brake, the construction in its entirety being simple and compara-- tively inexpensive.

The pockets we believe to be a new feature in vaultlight construction. They provide for a considerable depth of cement or concrete filling between the glasses, which is of special importance for the reason that a small shallow body or layer of cement does not have much bond or strength and readily breaks up or crumbles. Since also the pockets ol' cement extend below the bars B and between the carrying bars 'A it forms a brace similar in effect to bridging between joist or beams in carpentry and prevents racking.

Vault lights are subjected'in traflic to much pressure from shifting loads and the prevention of a racking movement of the parts of the panel is important, land this is effected by our improvement.

The rod D employed to hold and strengthen the band of concrete between the glasses is also new in bar construction for vault lights.

Obviously the improvement is not limited to rods or. bars of a round form in cross section.

We are aware that the simple arrangement of wrought iron bars and rods is not new in itself, and we only claim it in combination as hereinafter pointed out.

1. In a vault light. the combination of n plurality of rows of glasses. a frame comprising carrying bars. a pair of transverse rods passing through the said bars between each pair of such rows, :i pocket supported on said rods.' and cement filling the pockef and space between the glasses.

2. In :l vault light, the combination of n frame coln prising a series of carrying bars, rows of glasses, co acting transverse rods :uljncentl the proximate edges of the rows. n plurality of :ilined pockels supported on said rods. said pockets sifunicd between and abutting against corresponding bars, and cement filling the pockets and spaces between the glass rows.

2i. In a vault light. the combination of :l frame comprising the carrying bars` transverse, rods. n pocket supported on Suid rods, glasses. and cement filling.r the pocket :ind space between the glasses. sziid pocket having flanges to embrace the rods, and la plastic filling between the fianges and rods.

4. ln :l vnult light, the combination of :i f'raiue comprisngl n series of carrying bars. rows of glasses, coacting transverse rods adjacent the proximate edges of the rows, n plurality of alined pockets supported on said rods, said pockets situated between and abutting against ceptacles suspended below the glasses, and n body of cement continuous between the glasses and from their Lipper level to a plaine below the rods, and n plastic cushion between the glasses and rods.

In testimomv whereof, we have signed this speeilem tion in l'he presence of two subscribingr witnesses.
